egfr.mdrd: Estimated GFR Using the MDRD Formula

Description Usage Arguments Details Value Author(s) References See Also Examples

View source: R/PCSmisc.R

Description

Computes estimated glomerular filtration rate (GFR) using the Modification of Diet in Renal Disease (MDRD) formula.

Usage

1
egfr.mdrd(..., scr.mg.dL, age.yr, is.female, is.black, bun.mg.dL=NULL, albumin.g.dL=NULL, scr.umol.L, scr.conversion.factor = 88.4)

Arguments

...

Ignored. This forces all parameters to be named, which is safer.

scr.mg.dL

Numeric. Serum creatinine in mg/dL.

age.yr

Numeric. Age in years.

is.female

Logical. TRUE for females, FALSE for males.

is.black

Logical. TRUE if race is 'black', FALSE otherwise.

bun.mg.dL

Numeric. Blood urea nitrogen (BUN) concentrations in mg/dL (optional).

albumin.g.dL

Numeric. Albumin concentration in g/dL (optional).

scr.umol.L

Numeric. Alternative specification of serum creatinine in umol/L.

scr.conversion.factor

Numeric. A factor for converting serum creatinine from umol/L to mg/dL.

Details

All arguments can be vectors. Albumin and BUN are optional. If they are specified, a more elaborate version of the MDRD equation is used.

Value

A numeric vector containing the estimated GFR mL/min.
